Brief Summary:
The purpose of this study is to compare the effects of the consumption of two different dietary patterns (low fat versus Mediterranean Diet) on the incidence of cardiovascular events of persons with coronary disease.

Condition or disease Intervention/treatment Phase
Myocardial Infarction Unstable Angina Malignancy Cognitive Decline Diabetes Mellitus Metabolic Syndrome Behavioral: Mediterranean Diet Behavioral: Low Fat Diet Not Applicable

Detailed Description:

Randomized clinical trial involving 1002 patients with coronary disease that are undergoing one of two diets in a randomized design (two groups; Mediterranean Diet 502 patients, Low Fat 500 patients) for 7 years. The two diets are: a)Low fat diet: <30% fat (12-14% monounsaturated fatty acids (MUFA); 6-8% polyunsaturated fatty acid (PUFA) ; <10% SAT) and b) Mediterranean Diet: >35% fat (22% MUFA; 6% PUFA ; <10% SAT).

Primary Objective:

Combined apparition of hard cardiovascular events (myocardial infarction, revascularization, ischemic stroke, documented peripheral artery disease or cardiovascular death).

Secondary Objectives:

Those related in the Outcome Measures section of this webpage
